Why cant a QToolButton be hidden after it is added to a QToolBar?

Question

This works...

QToolButton * toolbutton = new QToolButton(this);

//hide before addWidget
toolbutton->hide();

addWidget(toolbutton);

But this doesn't

QToolButton * toolbutton = new QToolButton(this)

addWidget(toolbutton);

//hide after addWidget
toolbutton->hide();

Is there an alternative so I can actually hide after a QToolButton after it is added to a QToolBar? I need to during runtime.

QAction * QToolBar::addWidget ( QWidget * widget )

You should hide returned QAction

Interesting suggestion. This would be an elegant solution if the majority of your toolbar items are QActions and only have one or two QWidgets on it. – Feb 19 '12 at 03:08
Even if you add QWidget to QToolBar it will return `QAction *` for it: `QAction * QToolBar::addWidget ( QWidget * widget )` – Kamil Klimek Dec 19 '12 at 08:58

One alternative is to add a QAction instead of a widget and then hide the QAction. I've tried it and it works with QAction::setVisible(false).

You can also do something like QToolBar::actions().at(3)->setVisible(false); if you know the position of the widget in the QToolBar.
